<li>早期的经典处理器</li>
</ul>
<p>包括了<code>ARM7</code>、<code>ARM9</code>、<code>ARM11</code>家族。</p>
<ul>
<li><code>Cortex-A</code>系列</li>
</ul>
<p>针对开放式操作系统的高性能处理器，应用于智能手机、数字电视、智能本等高端运用。例如<code>Cortex-A5</code>、</p>
<p><code>Cortex-A8</code>、<code>Cortex-A9</code>  、<code>Cortex-A15</code>、<code>Cortex-A53</code>。</p>
<ul>
<li><p><code>Cortex-R</code>系列</p>
<p>针对实时系统、满足实时性的控制需求，主要应于汽车制动系统、动力系统等方面。例如，<code>Cortex-R4</code>、<code>Cortex-R5</code>、<code>Cortex-R7</code>。</p>
</li>
<li><p><code>Cortex-M</code>系列</p>
<p>这系列的芯片为单片机驱动的系统提供了低成本优化方案，主要应用于传统的微控制器市场、智能传感器、汽车周边等方面。例如，<code>Cortex-M0</code>、<code>Cortex-M1</code>、<code>Cortex-M3</code>、<code>Cortex-M4</code>、<code>Cortex-M7</code>。</p>
</li>
</ul>
<h2 id="2-RISC和CISC"><a href="#2-RISC和CISC" class="headerlink" title="2. RISC和CISC"></a><font size=3>2. <code>RISC</code>和<code>CISC</code></font></h2><ul>
<li><code>RISC</code>处理器</li>
</ul>
<p>只保留常用的的简单指令，硬件结构简单，复杂操作一般通过简单指令的组合实现，一般指令长度固定，且多为单周期指令。这种处理器在功耗、体积、价格等方面有很大优势，所以在嵌入式移动终端领域应用极为广泛。</p>
<ul>
<li><code>CISC</code>处理器</li>
</ul>
<p>该种处理器不仅包含了常用指令，还包含了很多不常用的特殊指令，硬件结构复杂，指令条数较多，一般指令长度和周期都不固定。<code>CISC</code>处理器在性能上有很大优势，多用于<code>PC</code>及服务器等领域。</p>
<ul>
<li><code>SOC</code></li>
</ul>
<p><code>System on Chip</code>，即片上系统，将一个系统中所需要的全部部件集成在一个芯片中，它在体积、功耗、价格上有很大优势。</p>
<h1 id="二、ARM指令集概述"><a href="#二、ARM指令集概述" class="headerlink" title="二、ARM指令集概述"></a><font size=3>二、<code>ARM</code>指令集概述</font></h1><h2 id="1-指令"><a href="#1-指令" class="headerlink" title="1. 指令"></a><font size=3>1. 指令</font></h2><p>能够指示处理器执行某种运算的命令称为指令（如加、减等）。指令在内存中以机器码（二进制）的方式存在，每一条指令都对应一条汇编，我们所写的程序其实就是指令的有序集合。</p>
<h2 id="2-指令集"><a href="#2-指令集" class="headerlink" title="2. 指令集"></a><font size=3>2. 指令集</font></h2><p>处理器能识别的指令的集合称为<strong>指令集</strong>。不同架构的处理器指令集不同，指令集是处理器对开发者提供的接口。</p>
<h2 id="3-ARM指令集"><a href="#3-ARM指令集" class="headerlink" title="3. ARM指令集"></a><font size=3>3. <code>ARM</code>指令集</font></h2><p>大多数<code>ARM</code>处理器都支持两种指令集：<code>ARM</code>指令集和<code>Thumb</code>指令集。</p>
<ul>
<li><code>ARM</code>指令集</li>
</ul>
<p>所有指令（机器码）都占用<code>32bit</code>存储空间，它的代码灵活度高、简化了解码复杂度，执行<code>ARM</code>指令集时<code>PC</code>（程序计数器）值每次自增<code>4</code>。<code>ARM</code>指令集大概分为六种：</p>
<table>
    <tr><td align="left">数据处理指令</td><td align="left">进行数学运算、逻辑运算</td></tr>
    <tr><td align="left">跳转指令</td><td align="left">实现程序的跳转，本质就是修改了PC寄存器</td></tr>
    <tr><td align="left">Load/Store指令</td><td align="left">访问（读写）内存</td></tr>
    <tr><td align="left">状态寄存器传送指令</td><td align="left">用于访问（读写）CPSR寄存器</td></tr>
    <tr><td align="left">软中断指令</td><td align="left">触发软中断</td></tr>
    <tr><td align="left">协处理器指令</td><td align="left">操作协处理器的指令</td></tr>
</table>


<p>其中前三种是通用指令，也就是所有的处理器都有的指令，在<code>C</code>语言中都有相应的语句可以被编译成对应的指令，后三种是<code>ARM</code>专用指令，在<code>C</code>语言中没有相应的语句，所以不会有哪条<code>C</code>语言语句会被编译成后边三种指令。</p>
<ul>
<li><code>Thumb</code>指令集</li>
</ul>
<p>所有指令（机器码）都占用<code>16bit</code>存储空间，代码密度高、节省存储空间，执行<code>Thumb</code>指令集时<code>PC</code>值每次自增<code>2</code>。</p>
<h2 id="4-机器码与汇编"><a href="#4-机器码与汇编" class="headerlink" title="4. 机器码与汇编"></a><font size=3>4. 机器码与汇编</font></h2><h3 id="4-1-机器码"><a href="#4-1-机器码" class="headerlink" title="4.1 机器码"></a><font size=3>4.1 机器码</font></h3><p>机器码（二进制）是处理器能直接识别的语言，不同的机器码代表不同的运算指令，处理器能够识别哪些机器码是由处理器的硬件设计所决定的，不同的处理器机器码不同，所以机器码不可移植。</p>
<h3 id="4-2-汇编语言"><a href="#4-2-汇编语言" class="headerlink" title="4.2 汇编语言"></a><font size=3>4.2 汇编语言</font></h3><p>汇编语言是机器码的符号化，即汇编就是用一个符号来代替一条机器码，所以不同的处理器汇编也不一样，即汇编语言也不可移植。</p>
<h3 id="4-3-C语言"><a href="#4-3-C语言" class="headerlink" title="4.3 C语言"></a><font size=3>4.3 <code>C</code>语言</font></h3><p><code>C</code>语言在编译时我们可以使用不同的编译器将<code>C</code>源码编译成不同架构处理器的汇编，<code>C</code>语言是可以移植的。</p>
